MARS 16091 Potential Relay 322838-753 The Carrier CESO130028-00 Airflow SelectorThe MARS 16091 Potential Relay is a heavy duty, voltage sensing motor starting relay engineered for 1 3 HP single phase compressor applications. Built as a direct OEM replacement relay for Bristol and Copeland systems, this component is critical for managing the transition between start and run cycles. It utilizes back electromotive force (BEMF) to precisely disconnect the start capacitor once the motor achieves approximately 75 80% of its rated
